The distribution of the number of hours that a random sample of people spend doing
chores per week is shown in the pie chart. Use 32 as the midpoint for "30+ hours." Make
a frequency distribution for the data. Then use the table to estimate the sample mean and
the sample standard deviation of the data set.
